Heat, thunderstorms likely all weekend

It looks like monsoon moisture will flow into San Diego County from the south for much of the weekend, raising the humidity inland and sparking off thunderstorms, some of which might extend west of the mountains, says the National Weather Service. The chance of thunderstorms will be stronger on Sunday, but they could boom through inland areas both days. And it will be plenty hot, even though a weak marine layer hugged the coast at 8:30 a.m. today. The layer should be mostly gone by the time the annual San Diego Gay Pride Parade begins at 11 a.m. in Hillcrest. And it should be mostly clear when the San Diego Padres host the Colorado Rockies at Petco Park at 5:35 p.m. There could be some clouds lingering in the skies when racing begins at Del Mar at 2:05 p.m.

Here's a snap shot of forecast inland temperatures:

Surf: Jens and Adam over at Solspot.com say waves will be in the 2-3 foot range in South County through the weekend, and 3' plus in North County. Solspot: "Saturday will start off with mostly local windswell and S-SW background energy. There will be some long-period S-SSW swell (180-200) still filling in as we move through the day...the peak of the swell arrives as we move into the early part of the work week...but these forerunners should help add a little kick to the exposed spots."
